EEANS Fon NSULATING CANOPIES FOR SYSTEMS OF ELECTRICAL DIs'rRIBUrIoN.

Th all whom 'it may mmm:

Be it known that-I, GEORGE A. LU'rz, a citizen of the United States, andresident of Pleinfield, in the county of Union and State of New Jersey,have invented'ertaih new and useful Improvements in Means for InsulatingCenopies for Systems of Electrical specification.

The object of my invention is to provide simple and eflicient means forinsulating canopies from conduits,`out1et boxes and the like end wherebythe' insulating means will be adaptable to canopies of varyingdimens'ons. i

In carrying out m invention I provide blocks or pieces 'o insulatingmaterial adapted to be fitted and supported upon conduits for electric'cnducto-s, such as pipes, molding and the like, and against :whichblocks the canopies may bear to insulate them from the conduits andoutlet boxes.

My invention also comprises the novel details of improvement that willbe hereinafter more fully set forth and then pointed out in the claims.y y

Reference is to be had to the acconpaiying drawings fqrming part hcreof,wherein,

Figure 1 is a central sectional View of a portion of an electricalConduit system ema odying my improvements. Fig. 2 is a seetional Viewon-'the line 2, 2, in Fig. 1; Fig. 3 is a similar view of amodification; Fig.

' In the 'accompanying drawings the numeral 1 indicates a Conduit forelectric wires in the form of a pipe, as in Figs. 1, 2`und 3,

At 2 is an outlet 'orjunction -boxof any* be connected or'appliedin anywell known manner.

and conceal the outlet box and the adjacent ends of the conduits in'well known manner. 6 indicates blocks or pieces of insulatin materialas, for instance, porcelain, whic blocks are applied to theconduitsadjacent the outlet box, the anopy being fitted toor against saidinsulated blocks. Said blocks are shown provided withrecesses 6'receiving the ad aCent edges ofthecanopy, said recesses being shownfol-med in one edge of the blocks, whereby the blocks extend below theupper-edge of the canopy. Blocks 6 are rovded with transverse o enings 6whic receive the conduits. In' igs. 1 and 2 the openings 6 in blocks 6are so formed as to inclose or encircle theeonduits where'- 4 bytheblocks' are supported by and. .bang

u on the conduits, in which case the block i screws 7 set up against theConduit to hold the blo'ckin lace.

In Fig. 4 t e opening 6 is provided with oflset recesses46 to receivethe projectinp parts 1' of the conduit or molding, the block beingslipped along the conduit from its endbefore the'co'nduitis fitted inplace. 4

In` Fig. 5 the block 6 is provided on one side with a recess 6 toreceive the extended.

part 1 of the Conduit and the screw 7 fitted to the opposite side of theblock will engage the corr'esponding part 1 ofconduit 1 to retain' theblock t-hcreon, whcreby the block may be slippededgewise upon theconduit after the letter is fitted in place; y

v In Fig. 6 the opening.: G wide enough to pormit the block to beslipped odgewise upon the Conduit 1 while 'the letter is in place, and astrip 8, preferibly of metal, which engages the 'extended or groovedpurts 1 of (tonduit 1, receives a` screw 9 passing-through an opening inblock (3, wherely I the block is attached to the condit.

` 'By means 'of myimprovements the cnnopy 5 may be-thoroughly inslatedfrom theotlet box and from "the mndts by the blocks G which may beadjusted along the condnits transversely of the c'an'opy, wh-erebyeanopes .of 'different Lwidths mav be inslted from the conduits and seidblocks 'remain Suspended upon' the conduits, when` the canopy is removedBy means of my inprove-` supported by the coiduits foicome- Lion withthe eznopy. s
